Case 586 Rough Terrain Forklift: Base Platform 586 RT Forklift
The Case 586 Forklift is the base platform for one of Case's most successful lines of rough terrain forklifts — preceding the lettered C/D/E/G/H variants. Designed for heavy-duty lifting in construction, lumber, and material-handling applications, the original 586 established the chassis, mast, and drivetrain architecture that carried forward through every successor generation.
Where the 586 fits in the Case forklift line
The original 586 is the foundational platform for the 586-class line that ran through C, D, E, G, and H lettered variants. It sits above the 584 and 585 lines in chassis size and lift capacity, and serves as the predecessor to the 586C and every later letter generation.

Engine, hydraulics, and drivetrain
The original 586 runs a Case diesel through a power-shuttle transmission with mechanical front and rear axles. Heavier chassis than the 584/585 line, larger mast configurations available, and the platform that established the 586-class as Case's heavy-duty RT forklift backbone. The power-shuttle drivetrain — a defining feature on Case RT forklifts — gives the operator quick forward/reverse modulation without clutching, ideal for load-cycling work in lumber yards and construction sites.
Common service items on the 586

Need a part for your Case 586 Rough Terrain Forklift?
Power-shuttle components, mast cylinder seal kits, and brake/drivetrain cross-fit parts are the highest-value items on a 586. Call our parts team with your serial number.
Request a PartWhat to verify before ordering
- Serial number. Confirm the serial on the Case 586 forklift before ordering year-specific parts.
- Engine serial. Internal engine parts must match the engine serial number.
- Mast configuration. Lift height, carriage width, fork length, and side-shift options vary — confirm mast spec before ordering carriage / chain / cylinder parts.
- Two-wheel vs. four-wheel drive. Some Case RT forklift models are available in 2WD and 4WD configurations — drivetrain parts differ.
- Power-shuttle generation. Power-shuttle transmissions saw revisions — confirm by serial before ordering clutch-pack components.
Why the 586 still earns a paycheck
The original Case 586 established the platform for one of the longest-running RT forklift product lines in Case Construction's history. Foundation chassis, mast, and drivetrain architecture carried through generation after generation, and parts coverage remains strong because so many components cross-fit to the lettered C/D/E/G/H successors and the broader Case loader-backhoe / forklift / trencher product family.
Maintenance priorities on a 586 (base): clean fuel, power-shuttle oil quality, mast chain and lift cylinder service, brake service (A168790 cross-fit), and engine service per Case schedule. Broken Tractor maintains parts coverage for the original 586 alongside every later 586-class variant.
